INK-FOUNTAIN ooiisrnno'rron.

T 0 all whom it may concern:

Be it known that I, HENRY LANGE, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Ink-FountainConstructions, of which the following is a specification.

and 'a shaft for rotating the impeller of the fountain, whereby thefountain may be quickly and conveniently disengaged from. its base and anew one substituted. Certain details of structure are provided wherebythe operating shaft may be removed from the receptacle quickly andconveniently.

'Heretofore when it was desired to change inks, the ink fountains wereeither cleaned, washed and filled with ink, or the fountain, shaft andits bearing disassembled to remove the fountain. Because of the commonink fountain constructions this has been wasteful of time and requiresconsiderable labor. With my construction both labor and time are saved.

I have illustrated an embodiment of my invention in the accompanyingdrawing, in which:

Figure 1 is a front elevation of a portion of a printing press framewith an ink fountain mounted thereon.

Fig. 2 is a section as seen on the line 22 of Fig. 1.

Fig. 3 is a section as seen on the line 3-3 of Fig. 1.

Referring more particularly to the drawing, 5 indlcates the printingpress frame upon which is mounted a stationary bearing block 6, andastationary base for supporting the ink fountains indicated by 7. Thebearing block may be of any suitable construction. The supporting base 7is in the form of a channel with the legs turned upwardly and isprovided with a slot 8 extending longitudinally thereof. The fountain isof a common construction and it is merely necessary that it have animpeller sp fi re aten Patented-Jam14; 1919.

Application filed January 8, i917. SerialNo. 141.164.

splined to the shaft 11 by these interen, 3;ag-

ing' devices.

Secured to the bottom of'the inkreceptacle is a bolt 13 which isdisposed to extend through the slot 8 and is provided with a nut 14,whereby the ink receptacle may be.

disposed in proper position on the base 7 and fixed in position'at willby tightening the nut 14. The ink receptacle shown herein is of a kindwhichis suitable for hiking numbering heads used with presses. Shaft 11extends through bearing block 6 and mounted upon the shaft is a bushing15. Bushing 15 is provided with a thrust collar- 16, preferably integraltherewith and is secured to the shaft at will by means of a set screw17. Bushing 15 is journaled in the bearing.

To remove the ink fountain, set screw 17 is loosened permitting thewithdrawal of the shaft 11. WVhen it has been withdrawn from the inkfountain, nut 14 is removed from the bolt 13, permitting the inkfountain to be removed and replaced by another. Theposition of thebushing 15 when removed from the bearing block 6 is shown in dottedlines in Fig. 1. If it is merely desired to chan e the position of theink fountain along the supporting base, nut 14 is unloosened and the inkfountain may be moved along the supporting base to its new position.Bushing 15 permit the use of a key 12 co-extensive with the shaft. It isobvious that these changes may be made without stopping the operation ofthe press.

The ink cylinder 10, as is usual with fountains of this character,engages a distributing cylinder 18. The bearing block 6 may be mountedon a shelf 19 which extends from the frame, but any other suitable construction may be used.

What I claim is:

1. In an apparatus of the character described, in combination, astationary hearing, a bushing rotatable therein, an impeller shaftsupported in said bushing and movable longitudinally through saidbearing, said bushing and shaft having interengaging means whereby saidbushing is rotated with said shaft and is longitudinally movablerelative thereto, means adapted, at will, to fix said bushing and shaftagainst longitudinal movement relative to each other, an ink impellermounted on said shaft having means adapted to engage said engagingelement of said shaft to eflect rotation of said impeller by said shaftand permit longitudinal movement relative to said shaft, an inkreceptacle cooperatively associated with said impeller, a stationarybase on which said receptacle is removably supported and is adapted tobe adjusted, and means adapted, at will, to fix said receptacle and saidink impeller at different positions on said support longitudinally ofsaid shaft.

2. In an apparatus of the character described, in combination, astationary bearing, a bushing rotatable therein, an impeller shaftsupported in said bushing and movable longitudinally through saidhearing, said bushing and shaft having interengaging means whereby saidbushing is rotated with said'sh'aft and is longitudinally movablerelative thereto, means adapted, at will, to fix said bushing and shaftagainst longitudinal movement relative to each other, an ink impellermounted on said shaft having means adapted to engage said engagingelement of said shaft to effect rotation of said impeller by said shaftand permit longitudinal movement relative to said shaft, an inkreceptacle cooperatively associated With said impeller, a supportingbase comprising a channel in which the base of said receptacle removablyrests and along which it is adapted to be adjusted, and means adapted,at Will, to fix .said receptacle and impeller at different positions insaid channel longitudinally of said shaft, said bushing having ashoulder adapted to cooperate with said bearing to take the thrust onsaid shaft when said bushing is fixed to said shaft.

In Witness that I claim the foregoing I have hereunto subscribed my namethis 22d day of December, 1916.

HENRY LANGE.
